Lotsa roller chains will actually stretch faster than a stock single chain so research can be useful if in doubt of brand. I think RollMaster has good rep and offers a pre-stretched chain in at least some versions.An old trick that seemed to help was to submerge the new chain in oil that was heated to about 200 degrees for about an hour. A moly additive in the oil was suggested. This seems to have increased the life of the chain substantially. this probably only works on chevies so....
According to Isky..".. An excessively stretched chain can retard cam timing, as much as four cam degrees, because of the slack in the links. Also, even though most of the valve timing figures in this catalog are listed at split overlap, most of our camshafts are ground from one to two cam degrees advanced to allow for eventual stretch in the timing chain..."
